December: Winter Momentum and Offshore Windows
December wraps up the year in fine form. The average wave height is 2ft (0.6m), the period is 7.1s, and ideal wind is again 17%. The swell is weighted toward E (19.8%), ENE (18.7%), ESE (18.3%) and NE (14.0%), with the occasional 3-5ft (1-1.5m) pulse from ENE and NE. The biggest change is the wind: NNW (11.5%) and WNW (7.9%) combine with NW (7.9%) and W (5.7%) to give a robust offshore component, while onshore ENE/E/ESE/SE winds are less frequent than in fall. Cold fronts are the key players, and when a strong high pressure system settles over the Southeast after a front, expect sunny skies, offshore west winds and clean east swell peeling down the sandbars. Water temp is 19.2°C, air averages 16.4°C, and precipitation is 2.38 mm/day - winter surfing at its best.
